The healthcare sector has always been an early adopter and a great beneficiary of technological advances. The application of reinforcement learning, to the healthcare system, has consistently generated better results. Being a subfield of machine learning, reinforcement learning’s sole objective is to endow an individual’s skills in the behavioural decision making through the use of experience of the interaction with the world around them and create evaluative feedback. Contrary to the historically supervised learning methods which relied on one-shot, comprehensive and supervised reward indicators, the reinforcement learning approach entails a progressive decision making that is simultaneously sampled, evaluative and comes with delayed feedback. These unique features make the reinforcement learning technique an appropriate contender for developing prevailing solutions in various healthcare spheres. With this, diagnosing decisions or treatment regimens are often characterised by a lengthy and chronological procedure.

Recent approaches have yielded several barriers that exist with the application of reinforcement learning to the health care system. The fundamental challenges which are believed to be facing adoption of reinforcement learning include:
a. The impracticality of learning and evaluating purely observational data
Due to ethical and logistical reasons, it might not be possible to evaluate healthcare policies and make decisions based on outcomes that have just been averagely computed with no specific metrics.
b. Partial observability
Contrary to other popular belief, in medicine, it is almost impossible to observe everything taking place in an individual’s body. Not all signals will provide the ground truth about a patient. In such cases where sufficient data is not available, medical practitioners depend on calculated estimates.
Reward Function Concern
It’s often challenging to find a reward function that will balance temporary improvement with overall lasting success. With this, it’s difficult to determine which actions gave rise to the reward.
c. Issues of non-stationary data
By nature, healthcare data is itinerant and dynamic. Over time, treatment objectives are likely to change and evolve in a dynamic way that was not previously observed in the training data.
While reinforcement learning has led to great improvements in therapeutic development, diagnostics, and treatment commendations, there have also been several setbacks. As much as machine learning continues to offer the transformative potential for health and healthcare systems, some criticism revolving around it is highly merited as discussed below.
d. Data quality is critical yet overlooked
The quality of data obtainable to generate findings is usually dependent on the statistical procedures used and is also the key to success. Unsatisfactory data will not yield significant insights. Regardless of the sophistication of the analytical methods used, there are often some shortfalls in data adequacy. As much as there are high expectations with machine learning, it also has these shortcomings.
e. The results of machine learning must be reproducible
Algorithms of machine learning often perform better than other conventional arithmetical methodologies. Due to this, there is often a risk that the results will not be indicative of true or underlying causal processes.
f. Algorithms must be transparent
One of the most noticeable criticisms of machine learning methods is the fact that it represents a black box and offers no clear understanding of how acumens are generated. This brings about the risk of alchemy whereby users won’t understand why some algorithms work while others fail or the indicators used in selecting amongst different algorithm configurations.
g. Algorithms ought to be credible
The algorithms of machine learning must offer acumens which are reliable and associated with the scientific or clinical accord. If it fails to replicate established findings or conflicts with the proven indications, it’s more likely to be a methodological inaccuracy.
h. Algorithms must demonstrate impact
Since machine learning uses gains in performance compared to predictable statistical methodologies as grounds for claims of improvement, this approach is not always the correct standard. Testing the impact of the machine learning algorithm is always very important.
Reinforcement learning is a thrilling scope in the world of healthcare with its ability to regulate ultimate behaviours within a specific setting. Its adoption leads to a more detailed and accurate treatment at reduced costs.
Reinforcement learning, if well adopted is believed to bring about critical results in the coming years and will greatly impact the care and control of prevalent chronic ailments in influencing patient-centred health information with external influences comprising weather and economic dynamics or pollution exposure.
